Summary: When hurricanes become strong, they sometimes form a second eyewall around the main eyewall. This second ring of strong winds and heavy rain means that strong, damaging winds could cover a larger area than before. However, it also means that the storm might temporarily weaken. Understanding and predicting this process is therefore very important. …

Summary: The CYclone Global Navigation Satellite System (CYGNSS) was launched into space on December 15, 2016, to improve hurricane (tropical cyclone) forecasts by measuring wind speed on the ocean surface. Since the tropical cyclones mostly occur over oceans where other wind data are usually not available, the new observations can measure their wind speeds. This …

Summary: The warm ocean provides the energy for tropical cyclones to form and intensify. Knowing what is happening in the air immediately above this warm ocean (called the boundary layer) tells us how that energy gets into the air. So, it is important to know what is happening there to accurately predict how strong a …
